Inatially the whole things seemed overwhelming but I jus jumped in and found out that it is not that difficult to get results. Developing the skills to get professional results is another thing...LOL!
I bought a used enlarger, a 500mm enlarger lens for 35mm and a 90mm enlarger lens for my MF negatives. A few trays, a used safe light, easel and a used timer and I was in business. The whole investment was only about $200-250.
I paid about $100 for my Fujinon 90mm lens and 50-60 for my Nikon el-50mm lens.
I have zero knowledge about enlargers other than my enlarger which seems to be very well made but no one has ever heard of it. It is a Burleigh Brooks. I woould look on Ebay and when I found something that sounded good, I would post the name and model here and ask for opinions. I only paid $50.00 for mine so I said what is the worst that could happen????
Get a few books on the "how to basics" and have at it. This forum has been more help than you can imagine. I will confess that it is addictive! I hate sitting in front of the computer and using photoshop but I love sitting in a room lit only by the safe light and seeing the image appear in the tray!!!!!!!!!!
